Drug Testing and Analysis, EarlyView.Using targeted HILIC‐MS/MS metabolomics, inosine and hypoxanthine were identified as potential biomarkers of EPO administration. Their consistent and sensitive plasma responses highlight their promise for inclusion in the Athlete Biological Passport (ABP), warranting further investigation to enhance anti‐doping detection strategies. ABSTRACT Increasing

Diagnosis and epidemiology of red blood cell enzyme disorders
Thalassemia Reports, 2013 The red blood cell possess an active metabolic machinery that provides the cell with energy to pump ions against electrochemical gradients, to maintain its shape, to keep hemoglobin iron in the reduced (ferrous) form, and to maintain enzyme and ...

Metabolic changes during cardiac regeneration in the axolotl
Developmental Dynamics, EarlyView.Abstract Background The axolotl is a prominent model organism of heart regeneration due to its ability to anatomically and functionally repair the heart after an injury that mimics human myocardial infarction. In humans, such an injury leads to permanent scarring. Cardiac regeneration has been linked to metabolism and the oxygenation state, but so far,

Disruption of nucleotide biosynthesis reprograms mitochondrial metabolism to inhibit adipogenesis
Journal of Lipid ResearchA key organismal response to overnutrition involves the development of new adipocytes through the process of adipogenesis. Preadipocytes sense changes in the systemic nutrient status and metabolites can directly modulate adipogenesis.

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.
